Provider routing¶
The proxy routes requests to the correct provider based on the model field prefix.
How routing works¶
graph LR
A[Request: model=openai:gpt-4o] --> B{Parse prefix}
B -->|openai:| C[Inject OpenAI key]
B -->|anthropic:| D[Inject Anthropic key]
B -->|groq:| E[Inject Groq key]
C & D & E --> F[Forward to provider API]
F --> G[Return response]The proxy strips the prefix before forwarding so the provider receives the bare model name (gpt-4o, claude-sonnet-5, etc.).
Fallback routing¶
If a prefix is not recognised, the request is forwarded to the OpenAI-compatible endpoint configured as the default provider.
Per-workspace keys¶
Each workspace can have different keys for each provider. The proxy resolves the correct key by workspace API key → workspace → provider key lookup.
